Twitter Inc. (NYSE:TWTR): It appears that Twitter is rapidly shedding its formerly conservative initial public offering strategy; the company, which originally set its shares at a range that put it at a 27 percent discount over Facebook, has now raised its IPO price to $25 per share. The news leaves many investors skeptical given that Twitter’s membership base is currently a fifth the size of Facebook’s and the company isn’t anticipated to make money until 2015.

Facebook Inc. (NASDAQ:FB): Facebook-owned Instagram will begin running advertisements starting Friday, with the first official ads debuting from fashion brand Michael Kors. The company has been ad-free for three years and is said to be approaching its new venture into monetizing the company with a “highly curatorial approach,” hoping to “deliver magazine-quality advertisements that it hopes audiences will enjoy.”
